Study Design:
Case report.
Objective:
To report a previously undescribed association between complex regional pain syndrome (CRPS) and surgery for cervical disc protrusion.
Summary Of Background Data:
Although CRPS has been associated with disc protrusion and lumbar spine surgery, there is no record in the literature of a similar association with cervical disc protrusion.
Methods:
Description of a clinical case.
Results:
A patient with radicular pain due to cervical disc protrusions underwent posterior foraminotomy, which did not relieve his pain. Within 3-4 weeks, he developed features of CRPS. Review at 16, 22, and 34 months revealed some, but limited, improvement.
Conclusions:
This case provides circumstantial evidence of a hitherto undescribed association between CRPS and cervical disc protrusion. The mechanism is elusive, but may involve damage to small nerves in or near the intervertebral foramina.
